Since the second Bars-M was originally scheduled for launch in August 2015, I wonder why there has been a delay of seven months? Maybe the August date was in case the first Bars-M had a failure and a second one was ready to launch at fairly short notice?

The new launch should be Cosmos 2515, unless the Russians have twiddled the Cosmos numbers again.

That led to delays of about six weeks for the final launches in the Kobalt-M and Kvarts programmes, so I would have expected a similar delay to September 2015 for Bars-M #2 - pushing it to September-October 2015.
